As Rolf Landauer said "Computation is physical",

Yes, Landauer is a major proponents of that idea. If that is true, then computationalism is false.

I don't see that. I think it just requires a broader meaning of "physical" (which isn't well defined anyway).

You have to broaden "physical" so that 0 and his successors are physical object. But then the term "physical" has no more meaning at all, imo.
